    Question

    A person rows 300 km against the current in 5 hours and

    travels 540 km along the current in 6 hours. How much time will he take to row 660 km in still water?
    A 12.5 hrs Correct Answer Incorrect Answer
    B 8.8 hrs Correct Answer Incorrect Answer
    C 25.5 hrs Correct Answer Incorrect Answer
    D 22.5 hrs Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Upstream speed = 300 / 5 = 60 km/h

    Downstream speed = 540 / 6 = 90 km/h

    Speed in still water = (60 + 90) / 2 = 75 km/h

    Required time = 660 / 75 = 8.8 hours
